chore(web): regenerate agent docs for the integrated 0.10.3 batch

Ten independently reviewed slices (SEAM-2, REF-04, REF-08, first-run,
quota error, RU-15, release checklist, telemetry collector, Pet lockfile,
Rust 1.100.0 pin) merge onto main without conflict. The combined crate
surface changes the generated agent-docs index.

Validation: web check-facts and check-release-docs OK;
scripts/preflight.sh --check OK. Exact-SHA CI and RC dispatched.

CHANGELOG.md

@@ -7,8 +7,30 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ## [Unreleased]
 
+- **Removed (crate API):** the unwired `codewhale-hooks` dispatcher and its stdout, JSONL and Unix-socket sinks; `codewhale-core`'s `session`, `journal` and `ids` modules and the `hooks` argument of `Runtime::new`; `codewhale-runtime::resource_telemetry`; ten unreferenced public functions; and the duplicate `codewhale-agent` crate. `hook_sinks.unix_socket_path` still parses and is ignored. CLI, TUI and app-server behavior is unchanged.
+- **First-run setup:** installer downloads retry up to three times and remove partial files after a failed attempt. Folder trust uses 1 to trust, 2 to continue untrusted, and 3 or Esc to quit; letters do nothing. Provider pickers consistently say "needs key", and the unconfigured custom placeholder says "needs endpoint" while configured-route errors remain visible.
+- **Quota-window reset text:** a rate-limited turn now gives the reset time in plain words such as "19h29m" instead of Rust debug output like `Some(70168s)`, and leaves the reset clause out when the provider gives no reset time. An OpenCode Go message points at that provider's own key with `codewhale auth set --provider opencode-go`, without repeating a hint the message already carries. (CW-8209)
+- **Usage-reporting collector:** accepts runtime schema 6 alongside existing versions and keeps schema 6 reports first-party only.
+
+- **Source-build toolchain:** Rust 1.100.0 is pinned consistently across local source builds, CI, Docker, Dev Containers and CNB recipes. The minimum supported Rust version remains 1.89.
+- **Plugin index hooks:** hooks with the same name and event now have distinct row IDs, so clients can keep every configured hook visible.
+- **Extension service approvals:** plugin service acts use the session permission gate and retain their approved or refused act records when a tool call fails. Closing a call seals its broker-act record so a late approval cannot authorize an unrecorded act. Ordinary nested-call receipts may still show an in-flight outcome when cancellation ends the call early.
+
+- **Renaming sessions with Chinese titles:** the session picker no longer rejects a Chinese, Japanese, Korean or emoji title of more than about 33 characters as "Title must be 1–100 characters". It now counts characters, as the message says and as `/rename` and the Runtime API already did, so any title up to 100 characters is accepted. Thanks [@luochen211](https://github.com/luochen211) (PR 7322).
+- **Non-ASCII file names:** `/diff`, the `@git` and `@diff` mentions and the Runtime API workspace diff now show paths with Chinese, emoji and other non-ASCII characters as written instead of as quoted octal escapes, and the turn context no longer lists the workspace root as an empty "Active paths" entry. Thanks [@luochen211](https://github.com/luochen211) (PR 7317).
+- **Session names after a crash, and keep-forever snapshot retention:** a session name saved right after a crash that cut off the previous session-index line is no longer lost, because the new entry now starts on its own line; and a very large `[snapshots] max_age_days` (such as `9223372036854775807` for "keep forever") no longer wraps around and deletes every undo snapshot at session start. Thanks [@luochen211](https://github.com/luochen211) (PR 7316).
+- **Blank environment variables:** exporting a variable empty (for example `CODEWHALE_MODEL=` from a compose `${VAR:-}` template) no longer hides its legacy alias. `DEEPSEEK_MODEL`, `DEEPSEEK_BASE_URL`, `KIMI_BASE_URL`, `DEEPSEEK_FORCE_HTTP1`, `DEEPSEEK_STREAM_OPEN_TIMEOUT_SECS` and the other provider alias variables now apply as they do when the primary is unset. Thanks [@luochen211](https://github.com/luochen211) (PR 7315).
+- **MCP and language servers that send requests mid-call:** a tool call no longer fails with "neither a result nor an error" when an MCP server sends a `ping` or other request that reuses the call's id while the call is running, and a language server's `workspace/configuration` or similar request no longer ends a pending LSP request. Codewhale now answers `ping`, answers other server requests with "Method not found" (it never advertised them), keeps waiting for the real reply, and a refused answer over Streamable HTTP no longer drops the connection to legacy SSE. Thanks [@luochen211](https://github.com/luochen211) (PR 7319).
+- **Qwen Code as an external agent:** Codewhale now finds an installed Qwen Code CLI (`qwen`, 0.6.1 or newer) and can run it as a session over ACP with `qwen --acp`. `GET /v1/agents/external` lists it, an older install is reported as needing `npm i -g @qwen-code/qwen-code@latest`, and sign-in stays inside Qwen Code (`/auth`). Thanks [@MannXo](https://github.com/MannXo) (#7293).
+- **Qwen Code as an external agent:** Codewhale now finds an installed Qwen Code CLI (`qwen`, 0.6.1 or newer) and can run it as a session over ACP with `qwen --acp`. `GET /v1/agents/external` lists it, an older install is reported as needing `npm i -g @qwen-code/qwen-code@latest`, and sign-in stays inside Qwen Code (`/auth`). Thanks [@MannXo](https://github.com/MannXo) (PR 7293).
+- **Telemetry setting default:** the settings schema API reports telemetry's default as on, matching what Codewhale does when you have not chosen.
+- **Auto routing abstention:** when the decision model marks a tier, effort or shadow answer `abstained: true`, Auto no longer acts on it, even with `min_confidence = 0`: an abstained tier takes the local fallback, an abstained effort keeps the tier and drops only the effort, and the routing receipt lists the abstained questions.
+- **Plugin index (Runtime API):** a new `GET /v1/apps/plugin-index` route lists plugins, skills, connectors, hooks and hand-written commands with kind, source and state, and `/v1/commands` rows say which plugin (`plugin_id`) added a command and whether a command came from the project (`workspace_sourced`) (CW-8092).
+- **Model commands and routing:** `codewhale model list` now lists every custom endpoint you have configured, under its own name. `codewhale model resolve` no longer refuses a model on a custom endpoint, router or local server whose model list has not been fetched yet; once a list is fetched, a model missing from it is still refused. Automatic routing marks a context window as verified only when the route itself supplies it, and no longer reports a guessed output limit.
+- **ACP:** when a plugin tool asks the core to run a tool that needs approval, the editor now gets a `session/request_permission` on the plugin tool's call that names the nested tool and its input; before, the prompt ended with an internal error (CW-8050).
 - **README and contributor credit:** the repository front page now opens the way the website does: the line "The model can be anyone's. The agent should be yours.", one sentence on what Codewhale is, the install command and one picture, with reference detail moved into the linked guides; the 18 translated READMEs follow the same structure and say they are machine-drafted. The contributor wall and the website now count the same 433 people (407 GitHub accounts and the commit authors whose email is not linked to an account), where the website had counted accounts only. `DEPENDENCY_SECURITY.md` moved into `docs/dependency-maintenance.md`, and `.github/SUPPORT.md` says where to ask for help.
 - **Website Plugins page:** The website's Plugins page now describes what the released version does, and a labelled section says what 0.10.3 adds: one Plugins place, Standard and Creator mode, and the Permissions control.
+- **First-time guide on the website:** a new docs page, "Use Codewhale for the first time" (`/docs/first-time`, English and Simplified Chinese), walks someone who has never used a terminal through opening one, installing, choosing the folder Codewhale works in and when that choice matters, opening a terminal in a folder from Finder or File Explorer, connecting a model, a first task, and stopping, undoing and quitting. The install page gains a short "New to the terminal?" block for macOS and Windows that links to it, and `llms.txt` carries the same steps.
 - **Plugin docs and plugin-creator:** Docs now say everything you add is a plugin. The bundled plugin-creator skill no longer tells an agent never to trust or enable a plugin (in Full Access it may, for one it wrote and installed from its project), points code and screen plugins at cordis-plugin-development, and an untouched copy from 0.10.2 now upgrades. The Chinese extension and Runtime API docs now say editor ACP sessions get plugin tools and configured MCP servers.
 - **Model thinking:** New installs show model thinking by default: it streams live in the transcript and collapses under a "Thought for …" header when the answer starts. Existing installs keep their saved setting; turn it on under Model reasoning in chat in /config.
 - **Footer clock:** The footer clock and phase now say "thinking", matching the transcript.
